Hi All,
Have recently got my original system replaced with a cat back 2.5 inch system and I'm damn happy with the results.
Engine really starts pulling @ 2100rpm and 3/4th gear pulls hard right through to 3500rpm, overtaking on highway is a breeze now and towing my boat or camper is no longer a chore.
Haven't Noticed any change in fuel figures yet but I guess there must be some improvement.
System is straight thru no muffler, snorkel and K&N air filter sounds nice at idle but once on road no change to noise cost $400 fitted.
Cheers, Mick
